Hip

Normal Anatomy of the Hip joint

The thigh bone, femur, and the pelvis, acetabulum, join to form the hip joint.  The hip joint is a “ball and socket” joint.  The “ball” is the head of the femur, or thigh bone, and the “socket” is the cup shaped acetabulum. 

Femoro Acetabular Impingement (FAI)

Femoroacetabular impingement (FAI) is a condition where there is too much friction in the hip joint from bony irregularities causing pain and decreased range of hip motion. The femoral head and acetabulum rub against each other creating damage and pain to the hip joint. The damage can occur to the articular cartilage (the smooth white surface of the ball or socket) or the labral tissue (the lining of the edge of the socket) during normal movement of the hip.

Hip Fracture

The hip joint is a “ball and socket” joint.  The “ball” is the head of the femur, or thigh bone, and the “socket” is the cup shaped acetabulum.  The joint surface is covered by a smooth articular surface that allows pain free movement in the joint.

Avascular Necrosis

Avascular necrosis, also called osteonecrosis is a condition in which bone death occurs because of inadequate blood supply to it. Lack of blood flow may occur when there is a fracture in the bone or a joint dislocation that may damage nearby blood vessels.

Osteoarthritis of the Hip

Osteoarthritis, also called degenerative joint disease is the most common form of arthritis. It occurs most often in older people. This disease affects the tissue covering the ends of bones in a joint (cartilage). In a person with osteoarthritis, the cartilage becomes damaged and worn out causing pain, swelling, stiffness and restricted movement in the affected joint.

Hip Arthroscopy

Arthroscopy, also referred to as keyhole or minimally invasive surgery, is a procedure in which an arthroscope is inserted into a joint to check for any damage and repair it simultaneously.

Total Hip Replacement (THR)

Total hip replacement is a surgical procedure in which the damaged cartilage and bone is removed from the hip joint and replaced with artificial components.  The hip joint is one of the body's largest weight-bearing joints, located between the thigh bone (femur) and the pelvis (acetabulum).

Revision Hip Replacement

Revision hip replacement surgery is performed under general anesthesia. During the procedure, your surgeon will make an incision over the hip to expose the hip joint. Then the femur is dislocated from the acetabulum so that the old plastic liner and the metal socket can be removed from the acetabulum.
